Working Party on Multiphase Fluid Flow (WP MFF) presents best oral presentation awards to young scientists
Tereza Semlerová (University of Chemistry and Technology Prague, Czech Republic) and Christian Weiland (Hamburg University of Technology, Germany) were honoured with an award for the best presentation for their outstanding oral presentations at the International Congress of Chemical Engineering - CHISA 2024 in Prague in August 2024. Tereza Semlerová gave a lecture on the ‘Deformation and break-up of bubbles interacting with vortices in the presence of different surfactants’ and Christian Weiland reported on the ‘Development and implementation of a Lagrangian model for estimating bubble break-up in bubbling flows’. The award was announced by the Working Party on Multiphase Fluid Flow at the special session ‘Multiphase Flows in Bubble Columns’.
Congratulations to Tereza and Christian!

2019
WORKING PARTY ON MULTIPHASE FLUID FLOW Nominates Viktoria Wiedmeyer for Best POSTER AWARD
The EFCE Working Party on Multiphase Fluid Flow has named Viktoria Wiedmeyer, M.Sc., Max Planck Institute for Dynamics of Complex Technical Systems, Magdeburg, Germany, as the winner of the Poster Award 2019. The winning poster, "Crystal growth simulation in a continuously operated helically coiled tube" (by V. Wiedmeyer, A. Voigt and K. Sundmacher), was presented at the poster competition on fluid flow and multiphase systems at ECCE12&ECAB5, 2019 in Florence.
The award jury commented that Wiedmeyer’s group had presented an outstanding work that shows the successful modeling of crystal growth populations of large mean crystal size and narrow crystal size distribution. "The jury was especially impressed by Viktoria’s deep understanding of the physical fundamentals of crystal growth and their consideration in modelling", said Prof. Michael Schlüter, Chair of the Working Party on Multiphase Fluid Flow. EFCE congratulates Viktoria Wiedmeyer and co-authors for their great success. The Poster Award carries prize money of EUR 300.

Working Party on Multiphase Fluid Flow presents poster award to Maria Zednikova
The EFCE Working Party on Multiphase Fluid Flow has named Dr.Ing. Maria Zednikova, Institute of Chemical Process Fundamentals of the CAS, Prague, Czech Republic, as the winner of the Poster Award 2018. The winning poster, "Experiments on bubble breakup induced by collision with vortex ring" (by M. Zednikova, P. Stanovsky, T. Travnickova, J. Vejrazka), was presented at the poster competition on fluid flow and multiphase systems at CHISA 2018.
The award jury commented that Zednikova’s group had presented outstanding work that shows a novel experimental method to study the impact of flow structures on particle break-up. "The jury was especially impressed by Maria’s detailed and inspiring explanations during the discussion at the poster", said Prof. Michael Schlüter, Chair of the Working Party on Multiphase Fluid Flow. EFCE congratulates Maria Zednikova and co-authors for their great success. The Poster Award carries prize money of EUR 300.

Honorary Lecture for Philipp Rudolf von Rohr
During the 12th European Congress of Chemical Engineering in September 2019 in Florence, the long serving member of the Working Party on Multiphase Fluid Flow, Philipp Rudolf von Rohr, has been honored with a lecture given by Prof. Klavs Jensen from MIT Department of Chemical Engineering.
Philipp Rudolf von Rohr has been the head of the Institute of Process Engineering at ETH Zurich for several years since 1992 and chaired the department of mechanical and process engineering from 1999 until 2002. He studied mechanical engineering at the ETH Zurich, specialising in process engineering. The Swiss National Science Foundation granted him a scholarship to study small low-temperature systems at MIT in Cambridge, USA. At the end of 1985, he started working for a company in the field of process engineering apparatus and plant engineering with a focus on environmental technology. At the beginning of 1990 he took over the technical management of the company. In 1998 he founded the Laboratory for Transport Processes and Reactions. His research activities focused on three main areas: Transport processes, Plasma-assisted surface treatment processes and high-pressure processes on a micro- and macro-scale.
Philipp Rudolf von Rohr headed the EFCE Working Party on Multiphase Fluid Flow for several years and significantly contributed to its successful development. On behalf of the Working Party Multiphase Fluid Flow, the Chair, Prof. Michael Schlüter, thanks Philipp for his work and outstanding engagement for the scientific community and wishes him all the best for his future after retiring.
